      Bica, Eduardo Luiz Damiani; Alloin, Danielle Marie (1987) [Artículo de periódico]
      We present CCD spectra with 12.5 A resolution from 6300 to 9700 Å of 30 star clusters covering ranges 106 to 1.65 1010 yr in age, and -2.0 to 0.1 in metallicity, [Z/Zʘ]. As well, 62 galactic nuclei have been observed in ...
